THE U23i
The U23i was designed with a singular intent: to honor the classic performance runabout
while redefining what it can be today. Its proportions are deliberate. Its surfaces restrained.
Every line serves a purpose—balancing elegance with authority, tradition with modern engineering.
Nothing is added without reason. Nothing distracts from the experience.
Handcrafted in Manistee, Michigan, the U23i delivers confident inboard performance
with composure and control. Power is smooth, immediate, and refined—
engineered to engage the driver and reward time spent at the helm.
This is not a reinterpretation driven by nostalgia.
It is a modern expression of timeless principles: precision, balance, and craftsmanship.
Materials are chosen for longevity. Engineering decisions are made for performance.
Details are finished for those who notice them.
The U23i is built for owners who value how something feels as much as how it looks—
and who understand that true luxury is never loud.
A modern-day classic.
Purpose-built.
Enduring by design.

OUR HISTORY
Along the eastern shore of Lake Michigan stands Manistee—an unassuming town defined by water, discipline, and a quiet standard of excellence. Beginning in 1928, it became a place where boats were not assembled, but crafted—by hand, by artisans, and without compromise. Each hull reflected precision, balance, and purpose, earning admiration far beyond the Great Lakes.
As with many great traditions, time intervened. By 1987, the last molds were set aside, and a once-proud boatbuilding heritage fell silent.
But legacies do not disappear. They wait.
In 2019, the craft returned—guided by decades of experience, a shared philosophy, and a belief that true luxury is built, not rushed. From this revival, Thoroughbred Boat Company was born, reestablishing Manistee as a destination for discerning owners who value design integrity, performance, and enduring quality.
Today, Thoroughbred Boats represent a modern interpretation of classic principles. Clean lines. Thoughtful engineering. Materials chosen for both beauty and longevity. Each boat is designed with restraint, built with intention, and finished to standards that reward those who appreciate the details others overlook.
This is not a reinvention. It is a continuation—of a legacy shaped by water, refined by time, and once again crafted in Manistee, Michigan.


OUR JOURNEY
The finest machines are not created to follow trends. They are built with purpose, shaped by experience, and refined over time.
Thoroughbred boats are modern interpretations of classic performance runabouts—crafted by hand in Manistee, Michigan, where boatbuilding tradition runs deep. Each design reflects a disciplined balance of form and function, combining timeless proportions with contemporary engineering and materials.
Behind every Thoroughbred is a team with generations of marine experience, united by a belief that true luxury is found in precision, restraint, and how a boat performs on the water—not in excess.
This is not nostalgia. It is continuity.
A modern-day classic, built to endure.
